2024-11-24Auto merge of #132791 - tyilo:big-file-fail-fast, r=compiler-errorsbors-1/+10
rustc: Fail fast when compiling a source file larger than 4 GiB Currently if you try to compile a file that is larger than 4 GiB, `rustc` will first read the whole into memory before failing. If we can read the metadata of the file, we can fail before reading the file.

The previous commit updated `rustfmt.toml` appropriately. This commit is the outcome of running `x fmt --all` with the new formatting options.
2024-07-18Be more accurate about calculating `display_col` from a `BytePos`Esteban Küber-2/+0
No longer track "zero-width" chars in `SourceMap`, read directly from the line when calculating the `display_col` of a `BytePos`. Move `char_width` to `rustc_span` and use it from the emitter. This change allows the following to properly align in terminals (depending on the font, the replaced control codepoints are rendered as 1 or 2 width, on my terminal they are rendered as 1, on VSCode text they are rendered as 2): ``` error: this file contains an unclosed delimiter --> $DIR/issue-68629.rs:5:17 | LL | ␜␟ts␀![{i | -- unclosed delimiter | | | unclosed delimiter LL | ␀␀ fn rݻoa>rݻm | ^ ```

2024-04-23Rollup merge of #123993 - compiler-errors:coroutine-obl, r=lcnrLeón Orell Valerian Liehr-1/+1
Do `check_coroutine_obligations` once per typeck root We only need to do `check_coroutine_obligations` once per typeck root, especially since the new solver can't really (easily) associate which obligations correspond to which coroutines. This requires us to move the checks for sized coroutine fields into `mir_coroutine_witnesses`, but that's fine imo. r? lcnr
2024-04-16Construct `SourceMap` at the same time as `SessionGlobals`.Nicholas Nethercote-8/+18
Currently `SourceMap` is constructed slightly later than `SessionGlobals`, and inserted. This commit changes things so they are done at the same time. Benefits: - `SessionGlobals::source_map` changes from `Lock<Option<Lrc<SourceMap>>>` to `Option<Lrc<SourceMap>>`. It's still optional, but mutability isn't required because it's initialized at construction. - `set_source_map` is removed, simplifying `run_compiler`, which is good because that's a critical function and it's nice to make it simpler. This requires moving things around a bit, so the necessary inputs are available when `SessionGlobals` is created, in particular the `loader` and `hash_kind`, which are no longer computed by `build_session`. These inputs are captured by the new `SourceMapInputs` type, which is threaded through various places.

2023-11-02Minimize `pub` usage in `source_map.rs`.Nicholas Nethercote-43/+7
Most notably, this commit changes the `pub use crate::*;` in that file to `use crate::*;`. This requires a lot of `use` items in other crates to be adjusted, because everything defined within `rustc_span::*` was also available via `rustc_span::source_map::*`, which is bizarre. The commit also removes `SourceMap::span_to_relative_line_string`, which is unused.

2023-04-18Auto merge of #110083 - saethlin:encode-hashes-as-bytes, r=cjgillotbors-3/+3
Encode hashes as bytes, not varint In a few places, we store hashes as `u64` or `u128` and then apply `derive(Decodable, Encodable)` to the enclosing struct/enum. It is more efficient to encode hashes directly than try to apply some varint encoding. This PR adds two new types `Hash64` and `Hash128` which are produced by `StableHasher` and replace every use of storing a `u64` or `u128` that represents a hash. Distribution of the byte lengths of leb128 encodings, from `x build --stage 2` with `incremental = true` Before: ``` ( 1) 373418203 (53.7%, 53.7%): 1 ( 2) 196240113 (28.2%, 81.9%): 3 ( 3) 108157958 (15.6%, 97.5%): 2 ( 4) 17213120 ( 2.5%, 99.9%): 4 ( 5) 223614 ( 0.0%,100.0%): 9 ( 6) 216262 ( 0.0%,100.0%): 10 ( 7) 15447 ( 0.0%,100.0%): 5 ( 8) 3633 ( 0.0%,100.0%): 19 ( 9) 3030 ( 0.0%,100.0%): 8 ( 10) 1167 ( 0.0%,100.0%): 18 ( 11) 1032 ( 0.0%,100.0%): 7 ( 12) 1003 ( 0.0%,100.0%): 6 ( 13) 10 ( 0.0%,100.0%): 16 ( 14) 10 ( 0.0%,100.0%): 17 ( 15) 5 ( 0.0%,100.0%): 12 ( 16) 4 ( 0.0%,100.0%): 14 ``` After: ``` ( 1) 372939136 (53.7%, 53.7%): 1 ( 2) 196240140 (28.3%, 82.0%): 3 ( 3) 108014969 (15.6%, 97.5%): 2 ( 4) 17192375 ( 2.5%,100.0%): 4 ( 5) 435 ( 0.0%,100.0%): 5 ( 6) 83 ( 0.0%,100.0%): 18 ( 7) 79 ( 0.0%,100.0%): 10 ( 8) 50 ( 0.0%,100.0%): 9 ( 9) 6 ( 0.0%,100.0%): 19 ``` The remaining 9 or 10 and 18 or 19 are `u64` and `u128` respectively that have the high bits set. As far as I can tell these are coming primarily from `SwitchTargets`.
